2016-11-18[media] dvb: make DVB frontend *_ops instances "const"Max Kellermann
These are immutable. Making them "const" allows the compiler to move them to the "rodata" section. Note that cxd2841er_t_c_ops cannot be made "const", because cxd2841er_attach() modifies it. Ouch!

2016-10-21[media] dvb-frontends: don't break long linesMauro Carvalho Chehab
Due to the 80-cols restrictions, and latter due to checkpatch warnings, several strings were broken into multiple lines. This is not considered a good practice anymore, as it makes harder to grep for strings at the source code. As we're right now fixing other drivers due to KERN_CONT, we need to be able to identify what printk strings don't end with a "\n". It is a way easier to detect those if we don't break long lines. So, join those continuation lines. The patch was generated via the script below, and manually adjusted if needed. </script> use Text::Tabs; while (<>) { if ($next ne "") { $c=$_; if ($c =~ /^\s+\"(.*)/) { $c2=$1; $next =~ s/\"\n$//; $n = expand($next); $funpos = index($n, '('); $pos = index($c2, '",'); if ($funpos && $pos > 0) { $s1 = substr $c2, 0, $pos + 2; $s2 = ' ' x ($funpos + 1) . substr $c2, $pos + 2; $s2 =~ s/^\s+//; $s2 = ' ' x ($funpos + 1) . $s2 if ($s2 ne ""); print unexpand("$next$s1\n"); print unexpand("$s2\n") if ($s2 ne ""); } else { print "$next$c2\n"; } $next=""; next; } else { print $next; } $next=""; } else { if (m/\"$/) { if (!m/\\n\"$/) { $next=$_; next; } } } print $_; } </script> Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>

2015-06-09[media] dvb: Get rid of typedev usage for enumsMauro Carvalho Chehab
The DVB API was originally defined using typedefs. This is against Kernel CodingStyle, and there's no good usage here. While we can't remove its usage on userspace, we can avoid its usage in Kernelspace. So, let's do it. This patch was generated by this shell script: for j in $(grep typedef include/uapi/linux/dvb/frontend.h |cut -d' ' -f 3); do for i in $(find drivers/media -name '*.[ch]' -type f) $(find drivers/staging/media -name '*.[ch]' -type f); do sed "s,${j}_t,enum $j," <$i >a && mv a $i; done; done While here, make CodingStyle fixes on the affected lines.

2014-10-30[media] ds3000: fix LNB supply voltage on Tevii S480 on initializationUlrich Eckhardt
The Tevii S480 outputs 18V on startup for the LNB supply voltage and does not automatically power down. This blocks other receivers connected to a satellite channel router (EN50494), since the receivers can not send the required DiSEqC sequences when the Tevii card is connected to a the same SCR. This patch switches off the LNB supply voltage on initialization of the frontend.

2012-12-27[media] ds3000: bail out early on i2c failures during firmware loadRémi Cardona
- if kmalloc() returns NULL, we can return immediately without trying to kfree() a NULL pointer. - if i2c_transfer() fails, error out immediately instead of trying to upload the remaining bytes of the firmware. - the error code is then properly propagated down to ds3000_initfe().

2012-11-22[media] ds3000: remove useless 'locking'Rémi Cardona
Since b9bf2eafaad9c1ef02fb3db38c74568be601a43a, the function ds3000_firmware_ondemand() is called only once during init. This locking scheme may have been useful when the firmware was loaded at each tune. Furthermore, it looks like this 'lock' was put in to prevent concurrent access (and not recursion as the comments suggest). However, this open- coded mechanism is anything but race-free and should have used a proper mutex.
